tablet 55, fourth: the engine answers the whole dialectic over the wire

Live after vav :4bffa01e the judges consulted with roots the engine
could read — interpret found 4 mitzvot and 11 verses for bereishit 1:1
— and the other two seats still said teiku. The engine had no
"challenge" action at all (process_json_line failed and the socket
fell silent), and a resolve that SUCCEEDED came back
UNEXPECTED_RESPONSE because response(ok, resolved_accepted, ...) had
no JSON clause. Both pre-existing; both invisible until a judge asked.

- api.pl: request(challenge, ...) — interpret, then a kushya against
  it → resolved_challenged with the kushya; none → no_challenge with
  the reading.
- json_bridge.pl: interpreted | resolved_accepted | no_challenge share
  the "resolved" JSON; resolved_challenged now carries the
  interpretation's verses and mitzvot (a judge rejecting on the kushya
  cites its ground); resolved_synthesized and no_interpretation gain
  clauses.
- reasoning_test.pl: dialectic_over_the_wire — all three actions
  answer; no roots → resolved on an empty trace (the judge abstains).

Prolog: 7 suites green (bedikah 45, halt 49, middot 47, mitzvot 42,
phase3 28, reasoning 18, tzaraat 34). Local probe: interpret /
challenge / resolve each → resolved, 11 verses, 4 mitzvot.

Live proof waits for tomorrow's manna: today's five panels were all
spent on verification (503 MANNA_DEPLETED, as specified).
